Nizoral (Ketoconazole)

Ketoconazole, the active ingredient in Nizoral, is an azole antifungal presented as a topical preparation for skin use. It is employed to treat a range of superficial fungal infections in adults and children, targeting the causative dermatophytes and yeasts on the skin surface.

GNH USA supplies Nizoral as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides regulatory‑approved batches to meet global demand.

Ketoconazole is used topically to manage fungal skin conditions by inhibiting the growth of dermatophytes and yeasts. - Athlete’s foot (tinea pedis): reduces itching and clears infection on the feet. - Jock itch (tinea cruris): alleviates redness and eliminates the fungal cause in the groin area. - Ringworm (tinea corporis): treats circular lesions on the body by eradicating the pathogen. - Seborrheic dermatitis: controls flaking and inflammation on the scalp and face. - Pityriasis versicolor: clears discolored patches caused by Malassezia species.

Topical ketoconazole may cause local and, rarely, systemic reactions.

Common Side Effects: - Skin irritation: mild redness or burning at the application site. - Itching: transient pruritus. - Dryness: localized skin dryness. - Scaling: mild flaking.

Serious or Rare Side Effects: - Severe allergic reaction: swelling, hives, or difficulty breathing. - Contact dermatitis: intense rash or blistering requiring medical attention.

When using Nizoral, consider the following safety measures. - Avoid use on broken skin: may increase systemic absorption. - Do not apply to eyes or mucous membranes: can cause irritation. - Limit treatment duration: prolonged use may lead to resistance. - Discontinue if severe irritation occurs: seek medical advice. - Store at room temperature: keep in original container, protect from moisture and direct sunlight.

Ketoconazole may interact with other medicines; monitor accordingly.

Major Interactions (Avoid): - Systemic azole antifungals (e.g., itraconazole): concurrent use may increase systemic ketoconazole exposure. - Strong CYP3A4 inhibitors (e.g., clarithromycin): may elevate plasma levels if absorbed.

Moderate Interactions (Monitor Closely): - Warfarin: topical use may potentiate anticoagulant effect; monitor INR. - Oral contraceptives: potential reduction in efficacy; consider alternative contraception. - Other topical irritants (e.g., corticosteroids): may increase skin irritation; observe for adverse reactions.
